Quiet Mind: when
emotions are still and there is no turbulence of the
mind. Then the Soul becomes a reflection of the truth, like a
still lake which reflects the objects in the sky. So the
self will reflect its
oneness with the
Self
(universe).

Quietness: is to
become observant of the external world, so to see its plays and
faults with an objective mind. It helps the aspirant to be more able
to achieve the truth about
Maya
(illusion of the external world).
